In the dynamic equilibrium between 2 phases, the total number of molecules in each phase stays constant (Option D).
When does dynamic equilibrium occur?
Dynamic equilibrium occurs when the direct and reverse rates are equal and the concentrations remain constant over time.
Which describes two phases in dynamic equilibrium?
- A. Molecules in one phase continually change to the other. NO. Molecules in both phases continually change.
- B. The total number of molecules must be equal in each phase. NO. This is not necessarily true.
- C. Molecules do not change from one phase to the other. NO. This would be a static equilibrium.
- D. The total number of molecules in each phase stays constant. YES. Since the forward and reverse rates are equal.
